Manufacturing Quality Control of 2,3-DIHYDROXYPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC-UV; identification and quantification based on relative retention times and response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, DMF) against calibration standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water; endpoint detected potentiometrically. |
| Heavy Metals | ICP-OES | Digestion followed by multi-element quantification via inductively coupled plasma optical emission spectrometry using characteristic atomic emission lines. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with conductivity detection; chloride quantified using external calibration. |
| Sulfate Impurity | Ion Chromatography | Same principle as chloride; sulfate eluted and quantified using conductivity detection and calibration standards. |
| Residue on Ignition | Gravimetric Analysis | Ignition of sample at 700-800 C to volatilize organic matter; residue weighed after cooling in desiccator. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode and pH meter. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using controlled heating and visual observation of meniscus movement. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against specified criteria under standardized lighting and viewing conditions. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution in dispersed phase. |
